After the shooting, the suspect called police and 27-year-old Kamuran Daniel Chabuk was booked into jail for investigation of assault. A handgun was seized from his home.

Chabuk made his first appearance Monday in Whatcom County Superior Court and bail was set at $200,000.

Western Washington University says Chabuk is a 2008 graduate who was working toward a master's degree in math. He has taught math classes at the university and had led a pre-calculus course this quarter. He's barred from campus during the police investigation.
